February, 1975, Survey of New-Protocol TELNET Servers
It has been two and a half months since our last survey, and it has
been depressing to note that "progress" toward an all-new-protocol
network has been even slower than previously. Changes since the last
list (with host numbers in octal):
SRI-ARC (2) and OFFICE-1 (53) have added logger sockets 27, but with
Old-Protocol servers (are these forerunners of New-Protocol
servers?);
SDC-CC (110) has been removed from the list until it starts operating
on the network
LL-67 (12) now has a New-Protocol server on socket 1;
CASE-10 (15) has departed from the network;
BBN-TENEX is now host 361 (formerly 105);
ANL (ARGONNE, 67) has come on the net with Old- and New-Protocol
servers on sockets 1 and 27, respectively.
The following is the latest version* of the summary and tabulation of
server-host Telnet servers.
total server hosts 36 100%
no New-Prot server 17 47%
unknown status (new host) 1 3%
total New-Prot implem. 18 50%
New-Prot on socket 27,
Old on socket 1 (2) 10 28%
New-Prot on 1 and 27 (3) 6 16%
New-Prot on 1 only (3) 2 6%
Notes:
* All data in this report were gathered via a surveying program run
at various times, plus a few manual checks to fill out the data.
What is reported here is the way the various servers work as seen
by the new-Protocol User Telnet at BBNA, as of 20 Feb. 1975.
(2) These are the sites whose operation is 100% correct according to
all protocols and conventions, as I understand them.
(3) We realize that some of the servers that appear here as New-
Protocol servers on socket 1 are actually servers which attempt
to communicate with both Old- and New-Protocol User TELNETs
according to what control sequences are received.
